Abstract: An internal dual band antenna meant for small radio devices. In one embodiment, the antenna contains two radiators and a parasite element, which is shared between them. The parasite element is implemented on three sides of the antenna module, which are perpendicular to the side where the two radiators are implemented. The short-circuit conductor of the parasite element extends close to the supply point/points of the antenna on the circuit board of the radio device and is connected to the ground plane of the radio device. The antenna structure is dimensioned such that the two resonance frequencies on both functional bands are at a lower frequency than the resonance frequencies of the actual radiators. Accordingly, both the lower and upper frequency band is widened. The shape of the parasite element does not weaken the adaptation of the antenna in either functional band.

The printed circuit board is at least partially disposed within the environmentally sealed housing and extends through a plurality of second order Hilbert Curves which are arranged in side-by-side relationship with one another.

Additionally, the length of the trace is limited by the space inside of the non-metallic structure, and therefore, depending on the size of the non-metallic structure, a very long trace having a high performance could be printed on the printed circuit board.
